Start the week with a documentary on polio from Stephanie Flanders, top tips from piercing interviewer Lynne Barber and the new instalment of Welsh detective drama Hinterland

For most of us in the developed world, the disease poliomyelitis belongs to a thankfully vanished world of paralysed children, calipers and iron lungs. But for Stephanie Flanders it still has a painful resonance. Her father Michael Flanders, of the musical double act Flanders and Swann, contracted the disease while serving in the navy, so the former BBC economics editor is well placed to tell the story of how the disease was ultimately defeated – in the developed world at least.

Everyone looks at everyone else in a meaningful way in this sullen, yet oddly engaging Welsh drama.Tormented DCI Tom Mathias (Richard Harrington) can’t even walk down a flight of stairs without looking as if he’s weighed down by existential angst. He is also the weepiest TV cop in history. Man up, Tom, for goodness’ sake.

One famous interviewer talking to another might seem like a niche proposition. But despite the journalistic self-indulgence, most viewers will enjoy Lynn Barber’s take on her career skewering celebrities. Her first memoir was made into the film An Education and her second – about her work – is insightful about the place where stardom and journalism meet.
